Be it known that I, CHARLES A. Goeswnnn, of Maquoketa, in the county of Jackson, in the State of Iowa,

have invented a. new and-useful Improvement in Cultivators; and I do hereby declare the following to be a full and exact description of the construction and operation of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which- Figure 1 is a perspective view. o My invention consists of attaching, to the bean: of any ordinary cultivator or'douhle-shovel p1ough,'the curved rod represented at'A,fig. 1; The rod A is secured to the standard 0 by means of the nut 13, and is fastened to the plough-beam by means of the eye F, the rod fitting the guide or eye loosely, allowing the rod free playjn an upward and downwarddirection, the nut H preventing the rod from slipping through the guide.

The operation of the machine is as follows r In the billing up of potatoes and other crops whose leaves and stems bend down to the earth, it is necessary to raise the stems of the plants to an upright position inorder to prevent them from being covered by the operation of the plough or cultivator. For this purpose the rod A is provided, and curved in the manner indicated in the drawing, for the purpose of lifting the stems and leaves of the plants to an upright'position in advance of the shovels of the plough. v

What I claim as my invention, and desire to secure by Letters Patent, 53- v The attachment of the curved rod A to the standard and Beam of the ordinary shovel-plough or cultivator, in the mannerand for the purpose above specified.
